  • Celestron C14 Optical Tube Assembly (CGE Dovetail)

    The Celestron C14 Optical Tube Assembly is an observatory-class instrument, delivering world-class views from its massive 355.5mm (14") aperture and 3910mm focal length. This OTA achieves a theoretical resolution of 0.33 arc seconds (Dawes Limit) and gathers 2581x more light than the human eye, revealing intricate details on planets and resolving faint deep-sky objects down to a limiting stellar magnitude of 15.3. Equipped with a CGE dovetail, this flagship optical tube is ready for installation on a high-capacity equatorial mount.

    14" Schmidt-Cassegrain: 0.33 Arc Second Dawes Limit

    The C14's optical power is defined by its immense 355.5mm primary mirror, which provides the light-gathering ability necessary to resolve fine details that smaller instruments cannot. This aperture allows the C14 to reach a Dawes resolution of 0.33 arc seconds, enabling you to clearly see Cassini's Division in Saturn's rings and resolve detail on the surface of Mars. The long 3910mm focal length is ideal for high-magnification views, and the included 40mm eyepiece provides an initial magnification of 98x for locating and centering objects.

    StarBright XLT Coatings: Maximizing Contrast and Transmission

    To ensure maximum light reaches your eye or camera sensor, the C14 features Celestron's premier StarBright XLT optical coatings. This advanced system uses enhanced multi-layer mirror coatings and multi-layer anti-reflective coatings on the corrector lens to dramatically increase light transmission and contrast. The result is visibly brighter images, deeper views into faint nebulae, and shorter exposure times for astrophotography. While all Schmidt-Cassegrains have a central obstruction, the C14's is held to just 10% by area, preserving the high-contrast views the design is known for.

    Imaging Versatility: From Native f/11 to Hyper-Fast f/2

    The C14 is a formidable imaging platform with two distinct personalities. At its native f/11 focal ratio, it excels at high-resolution planetary, lunar, and small galaxy imaging, leveraging its long focal length to achieve large image scales. For deep-sky imagers, the OTA is Fastar compatible, allowing the secondary mirror to be replaced with a third-party lens assembly. This converts the C14 into an incredibly fast f/2 astrograph, reducing exposure times by a factor of 25 and enabling the capture of vast nebulae in a fraction of the time.

    Observatory-Class Build: 46 lb OTA with CGE Dovetail

    Engineered for stability and performance, the C14's aluminum optical tube weighs 46 lbs and measures 787mm (31") in length. It comes equipped with a heavy-duty CGE-style dovetail bar for secure attachment to observatory-grade mounts. The package includes essential accessories to get you started, including a 9x50 finderscope for easy object location and a 2" star diagonal with a 1.25" adapter, providing flexibility for a wide range of eyepieces and accessories.

    Celestron C14 vs. C11: The Leap from 11" to 14" Aperture

    For observers deciding between Celestron's large SCTs, the choice often comes down to the C14 and its smaller sibling, the C11. The C11 is a superb instrument that is lighter and can be carried by less massive mounts. However, the C14 represents a significant step up in capability.

    • Light Gathering: The jump from an 11-inch to a 14-inch primary mirror provides a substantial increase in light-gathering power. This directly translates to brighter images, the ability to see fainter stars, and resolving more detail in the spiral arms of galaxies and the faint outer regions of nebulae.
    • Resolution: The C14's larger aperture gives it a superior resolving power, allowing for higher-magnification views of planets and the ability to split tighter double stars than the C11. For imagers, this means a higher level of achievable detail.
    • Mount Requirements: The C14's 46 lb weight demands a robust mount like a CGX-L or equivalent. The C11 is less demanding, making it a more portable option. The C14 is the choice for a permanent or semi-permanent setup where ultimate performance is the goal.
  • What kind of mount is required for the Celestron C14 OTA?

    The Celestron C14 OTA weighs 46 lbs (21 kg). It requires a heavy-duty equatorial mount with a payload capacity of at least 60-70 lbs for visual use, and preferably higher for stable astrophotography. Mounts like the Celestron CGX-L or Paramount ME are appropriate choices.

    How does the C14's Fastar capability work for astrophotography?

    The C14 is Fastar compatible, which means you can remove the secondary mirror and replace it with a separate lens assembly (sold by third parties like Starizona). This allows you to place a camera at the front of the telescope, imaging at the primary mirror's f/2 focal plane. This ultra-fast system is ideal for capturing wide-field, deep-sky objects with dramatically shorter exposure times compared to the native f/11 focus.

    Can I resolve Cassini's Division in Saturn's rings with the C14 OTA?

    Yes. Under steady seeing conditions, the C14's 14" aperture and 0.33 arc second Dawes resolution are more than sufficient to clearly resolve Cassini's Division, as well as subtle cloud bands on Saturn itself and details on Jupiter's surface like the Great Red Spot.

    What is the advantage of the C14's StarBright XLT coatings?

    StarBright XLT coatings are a premium multi-layer optical coating system that increases light transmission across the visual spectrum. This results in brighter, higher-contrast views. For visual observers, this means fainter stars and nebulae become visible. For astrophotographers, it means more light reaches the sensor in less time, allowing for shorter exposures.

    How does the C14 perform on deep-sky objects like the Andromeda Galaxy (M31) from a suburban location?

    The C14's massive 2581x light-gathering power is a huge asset in suburban skies. While it cannot eliminate light pollution, it can punch through the skyglow to reveal the bright core of the Andromeda Galaxy (M31) in stunning detail. With the included 40mm eyepiece (at 98x), you can frame the core and its surrounding dust lanes. Using the Fastar f/2 system with appropriate filters would further enhance the view for imaging, pulling out faint details even from a city.

    What is the main difference between this C14 and a Celestron EdgeHD 14"?

    The primary difference is the optical design's field flatness. This standard C14 is a traditional Schmidt-Cassegrain, which provides exceptionally sharp views in the center of the field. The EdgeHD version is an aplanatic Schmidt-Cassegrain that includes additional corrective lenses to provide a perfectly flat, coma-free field of view from edge to edge. For visual use the difference can be subtle, but for astrophotography with large-sensor cameras, the EdgeHD design is superior for achieving sharp stars across the entire frame.
